Application filed February 21, 1919. Serial No. 278,494.

To all whomit may concern:

Be it known that I, RUSSELL H. BREMER, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented new. and useful Improvements in Insulating-Linings, of which the following is a specification.

This invention relates to insulating linings for refrigerators, the object being to provide a lining which will absorb and retain cold air, so that when the refrigerator door is open fresh air entering will be immediately chilled by contact with the lining.

For this purpose the invention aims to provide a lining whose inner face is formed of a material preferably cement, which will readily absorb cold air, the cement having a suitable insulated backing, preferably formed of parchment paper, sawdust and asbestos, so as to prevent the escape of the cold air and thereby retain the absorbent facing in a chilled condition.

Another object of the invention is to provide a lining of the above character, which may be formed in blocks or slabs, the abutting edges of the blocks being covered by a metallic strip carrying hooks for supporting the contents of the refrigerator, the strips being secured in position by fastening devices passing between the edges of the blocks or slabs. The strips therefore serve the double purpose of acting as a retaining means for the blocks and as a supporting means for the contents of the refrigerator.

Other objects and advantages of the invention will appear as the following description is read in connection with the accompanying drawings.

In the drawings:

Figure 1 is a fragmentary elevation of a portion of the interior of a refrigerator compartment provided with an improved lining.

Fig. 2 is a sectional view of the same.

Referring to the drawings in detail, wherein like characters of reference denote corresponding parts, a portion of the refrigerator which may be of any wellknown construction or formation is illustrated and includes a standard 10 and the usual insulated wall 11. The standard 10 may form a portion of the frame of the door which provides an entrance to the compartment and the insulating wall 11 may be provided with the usual outer casing (not shown).

The invention resides in the provision of Specification of Letters reheat.

a combined absorbent and insulating lining, whichis preferably formed in blocks 12, the seams formedby the abutting edgesofethe blocks being covered by metallic strips13,"

' secured in position'by nails, screws, orother fastening devices 14, l the latter passing through the strips: and between the adjacent edges of the blocks andentering thewwall of the refrigerator. The strips, therefore, serve tojhold the blocks 12 in position and are further utilized 3 by providing hooks. 15, w'hich are carrieda the strips and serve as hangers .for: the contents of thetcomparta menu. it i w w I r The blocks 12 arexof novel construction, their innerpfaces being formed of a. suitable layer of absorbent material, preferably cement, as indicated at lfi. The porosity "of this material will serve to absorb and retain the cold air of the compartment and to prevent the escape of the air through the walls of the refrigerator. The layer of cement is provided with a backing com posed of a layer of'parchment paper 17, a layer 18 formed of a mixture of sawdust and glue and an additional layer 19 of parchment paper and a layer 20 of asbestos. This serves to prevent the passage of air, so that the cold air absorbed by the facing 16 will remain within the facing and when fresh air is admitted to the compartment through the opening of the compartment door, this fresh air will be immediately chilled by contact with the lining of the compartment, so that the latter will remain at all times in a thoroughly chilled condition, with a minimum consumption of ice.

If desired, the various layers of material which form the lining may be held together through the medium of a combined strip 21, arranged in zigzag formation, as indicated in Fig 2. By this means separate blocks of insulating lining are provided, which may be placed within the refrigerator compartment and held in the position in the manner previously described.

While the invention is shown and described in connection with refrigerators, it is here stated that this term includes refrigerators of every description, such as the usual household refrigerator, refrigerators. for ice boxes, for stores and for the lining of refrigerator cars, or in fact any place where it is desired to insulate a wall against the passage of either heat or cold.

It is believed that when the foregoing description is read in connection with the accompanying drawings, the construction and advantages of the invention will be apparent. The right is herein reserved to make such changes as properly fall within the scope of the appended claims.

Having described the-invention, what is claimed is:

1. An insulating lining formed of a layer of cement, a layer of parchment paper, a layer of saw-dust and glue and a layer of asbestos and means for holding the same together.

2. An insulating-lining formed of a layer of cement,'a layer ofparchment paper, a

layer of sawdustand glue and a metallic element for combining the various layers t0- gethe r. v

copies of this patent may be obtained for of cement, a layer of parchment paper, a layer of saw-dust and glue and a layer of asbestos secured together to provide separate insulating blocks arranged in abutting formation, a relatively narrow strip of material positioned over the seams formed by the meetingedges of the blocks and fastening devices passing through the strips and between the blocks to hold the latter in position.

5. An insulating lining formed of a layer of cement, a layer of parchment paper, a layer of sawdust and glue and a layer of asbestos secured together to provide separate insulating blocks arranged in abutting formation, a relatively narrow strip of material positioned over the seams formed by the meeting edges of the blocks, fastening devices passing through the strips and between the blocks to hold the latter in position and hooks carried by said strips to provide supporting means for the contents of the refrigerator.

In testimony whereof I aflix my signature RUSSELL H. BREMER.
